QUALITY OF EXPERIENCE ENHANCEMENTS OVER WIRELESS NETWORKS

摘要

Systems and methods for providing content-aware adaptation of multimedia communications in wireless networks to ensure Quality of Experience (QoE) of the content transmitted by the multimedia communications are generally disclosed herein. One example embodiment includes adaptive streaming optimization techniques, such as the exchanging of application-layer parameters used to establish network connectivity settings and implement an appropriate QoE for applications communicating within the wireless network. Example embodiments may also determine and implement Quality of Service (QoS) parameters for the wireless network and other connected networks based on the application-layer parameters. Such application-layer parameters may include receiver display capabilities and multimedia-specific parameters. These techniques may be used in connection with, for example, the transmission of real-time multimedia content, such as multimedia content communicated wirelessly from a computing device using a Wireless Display (WiDi) transmission standard.

主权项

1. A method performed by a transmitting device for adaptive streaming optimization within a wireless local area network, comprising:
determining target quality of service (QoS) parameters for an adaptive streaming communication within the wireless local area network from multimedia-specific parameters, receiver display capabilities of one or more receiving devices, and link conditions; and transmitting the adaptive streaming communication in the wireless local area network in accordance with the target QoS parameters; wherein the target QoS parameters are implemented using cross-layer adaptation among a plurality of network levels in the wireless local area network to provide quality of experience (QoE) for multimedia content to be delivered by the adaptive streaming communication.
